> Hi,
> Please review this fix to the implementation of section ` Allowed Narrowing Reference Conversion` of the Sealed Classes spec [1](http://cr.openjdk.java.net/~gbierman/jep397/jep397-20201204/specs/sealed-classes-jls.html#jls- IMO the compiler was not implementing the spec to the letter in particular the inheritance relation between a sealed class and a subclass should be tested ignoring type arguments which is what this patch is doing. Comments?
> Thanks,
> Vicente
